Hi dear listers Do you know how to made a mean by one or more categorical variables? I can do that quite easy on SAS by in R I just can't do it E.g. Some fishes Sex Lenght male 15 fema 20 fema 17 fema 19 male 18 So the idea is mean(Lenght) by sex, in order to have sex: Male mean=XX Sex: Fema mean=YY In this case is quite easy to do it by a loop, but I have a huge DB so is not an option. Any suggestion? Thanks in advance! -- Jorge Cornejo Donoso Universidad Austral de...

Hi again! Please try something like this: > zone1.df zone sex len 1 1 male 15 2 1 fema 20 3 1 fema 17 4 2 fema 19 5 2 male 18 > str(zone1.df) 'data.frame': 5 obs. of 3 variables: $ zone: Factor w/ 2 levels "1","2": 1 1 1 2 2 $ sex : Factor w/ 2 levels "fema","male": 2 1 1 1 2 $ len : int 15 20 17 19 18 > tapply...

Many thanks in advance, Yuelin Li. ps. part of the code came from a solution given by Deepayan Sarkar. ------------------- library(lattice) set.seed(12345) x <- 0:20 y.male.obs <- - 1.2 * x + 22 + rnorm(length(x), sd = 3) y.male.prd <- - 1.2 * x + 22 y.fema.obs <- - 2.2 * x + 30 + rnorm(length(x), sd = 2) y.fema.prd <- - 2.2 * x + 30 tdat <- data.frame(x = rep(x, 8), y = rep(c(y.male.obs, y.male.prd, y.fema.obs, y.fema.prd), 2), sex = rep(rep(c("m", "f"), each = 2*length(x)), 2), cohort = rep(c(&q...

About every 10th call coming into my x1000p is not getting the audio it should. You can see the messages scrolling on the console as they usually would, playing the thankyou, then and menu messages. internal phones ring, but when answered there is no audio. The caller gets a full volume echo with about 1/2 second latency. At first I thought it might be related to using the aggressive

The disaster in the Gulf coast and the less than optimal initial response suggests to me that citizens must shoulder more responsibility for emergency management.
